The control devices used in pneumatics are called ______.

• A. Cylinders
• B. Valves
• C. Actuators
• D. Piping

Answer: (B)

Valves are the control elements in a pneumatic system. They regulate how compressed air moves, deciding which path it takes, when it flows, and at what pressure, so the system can start, stop, or redirect motion as needed. Cylinders (or actuators) are the devices that convert the air’s energy into mechanical motion, so they respond to the valve’s command rather than control it. Piping is just the delivery network that carries air around the system, not a means of control. So the term that fits is valves.
